Over the course of a year, areas near Earth's equator receive more direct energy from the Sun than areas near Earth's poles. Which of the following describes one result of this heating power. *The poles lose all their heat at night.
*Atmospheric and oceanic currents disruptive heat from the tropics to the poles.
*Sunlight overheats the oceans near the equator making it impossible for sea life to exist there.
*Sunlight evaporates a massive amount of surface water near the tropics, creating flooding in this part of the world.

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero. 

The sunlight shines uv radiation on earth,a microwave oven radiates waves on food

To find speed, or mph, use distance/time.
